Spolostan 4G is an efficient dispersing agent for textile, rubber and plastic industries, suitable for use in dyeing, preparation and stabilization of dispersions. For its dispersing and levelling effect it is commonly used in the process of dyeing with PES disperse dyes, for levelling of basic dyes on PAN fibres and for levelling of anionic dyes on PAD fibres.
Spolostan 4G may also be applied in agriculture as a dispersing agent of pesticides and insecticides to provide wetting ability of dry powders into dispersible aqueous products, in paper industry to extract tall oil from black liquors, or in leather industry as a dispersant of insoluble tannings.
